Definitions

  • the invention relates to an exhaust gas cooler for an exhaust gas recirculation system and an exhaust gas recirculation system comprising such an exhaust gas cooler.
  • a cooler of this sort is known from EP 1 277 945 A1.
  • the cooler comprises a housing having ports to supply and discharge a coolant. Furthermore, a bypass pipe is provided bypassing the cooler in such way that the recirculated exhaust gas at least partially flows through the bypass pipe and is not cooled.
  • the invention among certain of its embodiments proposes an exhaust gas cooler and an exhaust gas recirculation system.
  • the exhaust gas cooler for an exhaust gas recirculation system comprises a total cooling power and a total pressure loss coefficient.
  • the exhaust gas cooler comprises at least one cooling portion having at least one cooling duct and at least one additional duct, at least one bypass bypassing one of the at least one cooling portion, and an exhaust gas routing device having at least one closing member.
  • the at least one cooling duct comprises a first cooling power and a first pressure loss coefficient
  • the at least one additional duct comprises a second cooling power and a second pressure loss coefficient.
  • the first cooling power is greater than the second cooling power and/or the first pressure loss coefficient is greater than the second pressure loss coefficient.
  • the closing member is suitable to increase the total cooling power coefficient and/or the total pressure loss coefficient by nearly preventing flowing of the exhaust gas in the additional duct.
  • This embodiment has the advantage that an additional third duty point is provided which can be easily removed by replacing the exhaust gas routing device by a conventional exhaust gas routing device, for example a standard deflecting manifold, if there is no need for such third duty point, for example, in an additional sales market.
  • the first two duty points are unaffected by this exchange.
  • the utilization of a precooler can be foregone. Thereby, a light and compact design of the exhaust gas cooler is possible.
  • a higher cooling power causes a lower outlet temperature of the exhaust gas to be cooled with a steady inlet temperature.
  • the pressure loss coefficient says something about which difference in pressure between inflow and outflow is needed for maintaining a certain flow through the component.
  • the exhaust gas cooler has at least two ducts running in parallel and suitable to be independently flowed through by exhaust gas, wherein a first conduit is connected to the cooling duct and the second conduit is connected to the additional duct, and wherein the closing member is disposed within the second conduit.
  • the first conduit and the second conduit are separated by a wall.
  • This embodiment presents the advantage that opening and closing of the closing member has no influence on the flow space of the second conduit, whereby the pressure loss coefficient of the cooling portion is unaffected by opening or closing the closing member.
  • This embodiment has the additional advantage that the exhaust gas supplied to the exhaust gas routing device by the cooling duct can be supplied to an additional cooling portion independently of the exhaust gases supplied by the additional duct.
  • the closing member is configured as a hatch or valve.
  • the closing member is arranged as a stroke valve.
  • the exhaust gas cooler comprises two cooling portions connected via the exhaust gas routing device.
  • the exhaust gas routing device comprises at least two parallel ducts which can be flowed through independently from each other by exhaust gas wherein the closing member is disposed within the second conduit and if the second conduit is supplied with exhaust gas via the additional duct by the cooling portion, the exhaust gases being passed on to an additional duct of a second cooling portion, the embodiment having two cooling portions is particularly advantageous. Therefore, the closing of the closing member causes the flow of exhaust gases to be interrupted at the same time within the additional duct of the first cooling portion upstream of the exhaust gas routing device and within the additional duct of the second cooling portion downstream of the exhaust gas routing device.
  • the cooling portions are flush in order to form a connecting surface engaging the exhaust gas routing device.
  • This embodiment has the advantageous effect that the exhaust gas routing device can easily be interposed between two cooling portions. Also this embodiment allows the exhaust gas routing device to be replaced by a simpler deflecting manifold in order to deactivate the third duty point, as desired or needed.
  • the exhaust gas cooler is formed as a U-cooler.
  • the cooler can also be formed as an I-cooler.
  • the exhaust gas cooler is characterized in that the closing member closes the additional duct of at least one cooling portion.
  • This embodiment involves the technical effect of preventing the flow of exhaust gas through the additional duct independently whether the closing member is disposed on the downstream or upstream side of the cooling portion.
  • the exhaust gas cooler is characterized by an inflow direction and an outflow direction, the inflow direction running approximately in parallel to and preferably extending in opposite direction to the outflow direction.
  • the cooling duct is provided with a cooling member which is preferably formed in a wavelike manner and which further preferably extends over the whole length of the cooling channel.
  • the cooling member can also be designated as a turbulator.
  • the cooling member can also be designated as “wellfin” or “winlet”.
  • the cooling member is suitable for causing turbulence of the exhaust gas flowing through the cooling duct.
  • This embodiment provides an improved cooling power of the cooling ducts. Furthermore, with this embodiment an additional duct can be transformed into a cooling duct by inserting an additional cooling member. Conversely, a cooling duct can be transformed to an additional duct by removing the cooling member.
  • This modular embodiment has the advantage that different duty points with different cooling powers can be provided without any additional construction effort and without changing the general design of the cooling portion, as desired. Merely the exhaust gas routing device, particularly the closing member, needs to be adapted accordingly.
  • cooling duct and the additional duct substantially have the same cross-section.
  • cooling ducts can be transformed to additional ducts and vice versa.
  • the cross-section is approximately constant over the whole length of the cooling duct and/or the additional duct. Since the pressure loss is caused by a cooling duct or an additional duct can be obtained depending on the cross-section of the component being flowed through, a constant cross-section facilitates the calculation of the length needed in order to achieve the pressure loss desired.
  • the cross-section is approximately rectangular.
  • the cross-section has the shape of an elongated hole.
  • the exhaust gas recirculation system according to the invention comprises an exhaust gas cooler according to the invention.
  • FIG. 1 a schematic view of the exhaust gas cooler according to the invention corresponding to a first exemplary embodiment

  • the exhaust gas cooler 10 comprises at least one cooling portion 20 , 20 ′, at least one bypass (not shown in the figures) and an exhaust gas routing device 40 .
  • the exhaust gas cooler 10 is composed of two cooling portions 20 , 20 ′ connected via an exhaust gas routing device 40 .
  • the exhaust gas routing device 40 is interposed between the first cooling portion 20 and the second cooling portion 20 ′.
  • the exhaust gases to be cooled enter the first cooling portion 20 in an inflow direction E and exit the second cooling portion 20 ′ in an outflow direction A.
  • the exhaust gas routing device 40 preferably reverses the flow direction of the exhaust gas.
  • the exhaust gas cooler 10 can be formed as a so-called U-cooler which can be manufactured with minimum space requirements, in particular.
  • the exhaust gas routing device 40 includes a closing member 42 which can be operated by operating member 43 .
  • the closing member 42 is suitable for shutting off the flow of exhaust gases through at least one additional duct 24 , 24 ′ of one of the cooling portions 20 , 20 ′. In a preferred manner, the closing member 42 closes the additional duct 24 , 24 ′ of both cooling portions 20 , 20 ′, as is illustrated in particular in FIGS. 4 and 5 of the second exemplary embodiment.
  • the exhaust gas routing device 40 comprises a wall 47 dividing the exhaust gas routing device 40 into a first conduit 44 and a second conduit 46 .
  • the closing member 42 only closes the additional duct 24 , 24 ′ of at least one of both cooling portions 20 , 20 ′. Due to the separation of both conduits 44 , 46 it is sufficient to close conduit 46 either on the input or the output thereof. As particularly depicted in FIG. 3 , the two conduits 44 , 46 are formed by the wall 47 .
  • the closing member 42 of the exhaust gas routing device 40 interposed between two cooling portions 20 , 20 ′ closes the output of the additional duct 24 of the first cooling portion 20 and at the same time the input of the additional duct 24 ′ of the second cooling portion 20 ′.
  • the exhaust gas routing device 40 is interposed between the first cooling portion 20 and the second cooling portion 20 ′ in the direction of flow of the exhaust gas.
  • the surface forming an outlet opening of the first cooling portion 20 and the surface forming an air inlet opening of the second cooling portion 20 ′ together constitute a connecting surface 30 along which the exhaust gas routing device 40 is disposed.
  • the exhaust gas routing device 40 can be interposed between the first cooling portion 20 and the second cooling portion 20 ′ by putting the exhaust gas routing device 40 on the connecting surface 30 , in a simple manner.
  • the cooling portion 20 , 20 ′ comprises five cooling ducts 22 , 22 ′ and an additional duct 24 , 24 ′, respectively.
  • a cooling member 25 is provided, respectively, causing turbulence of the exhaust gas flowing through the cooling ducts 22 , 22 ′, thereby increasing the cooling power of the cooling ducts 22 , 22 ′.
  • the cooling ducts 22 , 22 ′ differ from the additional ducts 24 , 24 ′ solely by the presence or the absence of a cooling member 25 .
  • the cross-section of the cooling ducts 22 , 22 ′ and the additional ducts 24 , 24 ′ is otherwise the same. As particularly shown in FIG. 1 a , the cooling ducts 22 , 22 ′ and the additional ducts 24 , 24 ′ substantially have a cross-section which is approximately rectangular, and preferably has the shape of an elongated hole.
  • This embodiment of the exhaust gas cooler 10 allows for the transformation of cooling ducts 22 , 22 ′ into additional ducts 24 , 24 ′ by removing the corresponding cooling member 25 from the cooling duct 22 , 22 ′, in a variable manner.
  • the additional duct 24 , 24 ′ can be transformed to a cooling duct 22 , 22 ′ by inserting a cooling member 25 into the additional duct 24 , 24 ′.
  • the exhaust gas cooler 10 can be set to different duty points by varying the number of ducts 22 , 22 ′, 24 , 24 ′ used as additional ducts 24 , 24 ′.
  • the exhaust gas cooler 10 is preferably utilized when the exhaust gas cooler 10 is installed in a motor vehicle intended for different sales markets involving different requirements for the exhaust gas cooler 10 .
  • the cooling ducts 22 , 22 ′ and the additional ducts 24 , 24 ′ as well as the length of the cooling portions 20 , 20 ′ are selected in such a way that two duty points can be provided complying with the requirements of one of the sales markets, when the cooling portions 20 , 20 ′ are connected to a standard deflecting manifold (including the duty point provided by the bypass pipe) instead of the exhaust gas routing device 40 .
  • a standard deflecting manifold including the duty point provided by the bypass pipe
  • the exhaust gas cooler 10 is supplied with 100 kg exhaust gas per hour at a temperature of 450° C.
  • the temperature of the surface oriented outwards of the cooler is 95° C. If the exhaust gas cooler 10 is operated with the closing member 42 being opened (duty point 2 ), a pressure loss of 27.5 mbar is achieved with the outlet temperature of the exhaust gas being 201° C. Whereas with the closing member 42 (duty point 3 ) being closed, a pressure loss of 53 mbar is achieved, and the outlet temperature is only 174° C.
  • the total cooling power P G is substantially lower with the closing member 42 being opened compared to the closing member 42 being closed.
